On Windows NTFS symlinks are implemented as reparse points,
which are special kinds of files *or directories*. A directory
symlink should link to a directory. A file symlink should link
to a file. Mismatching (such as a file symlink pointing to a
directory) produces symlinks that simply do not function.
Therefore GFileType file vs directory vs symlink distinction is
too simplistic to correctly represent a NTFS filesystem object type.
Since we can't turn back time and choose a better way of representing
file types, make GFileType reflect the file vs directory type on
Windows, meaning that all FS objects are either files or
directories (or shortcuts, which are also files), but never symlinks.
A test for symlinkiness will have to be made via GFileInfo - it
tracks symlinkiness separately from file/directory/whatever.
1) Remove the non-Windows-only condition for subdir('tests').
2) Add libiphlpapi, libws2_32 and libsecur32 deps, needed for W32 tests.
3) Remove the -no-undefined argument (gcc doesn't understand it,
it *does* understand -Wl,-no-undefined; either way, the test
compiles without this argument just fine; maybe meson adds it
by itself - you can hardly build shared modules without it).
4) Add or fix a number of includes
5) Disable gdbus-objectmanager tests when building with MSVC
(right now these tests don't work on Windows anyway, so the fact
that MSVC can't even build them properly is irrelevant;
most likely gdbus-codegen needs changes to put _GLIB_EXTERN
before each function)
This commit adds new W32-only functions to gstdio.c,
and a new header file, gstdioprivate.h.
These functions are:
g_win32_stat_utf8()
g_win32_lstat_utf8()
g_win32_fstat()
and they fill a private structure, GWin32PrivateStat,
which has all the fields that normal stat has, as well as some
extras.
These functions are then used throughout glib and gio to get better
data about the system. Specifically:
* Full, 64-bit size, guaranteed (g_stat() is forced to use 32-bit st_size)
* Full, 64-bit file identifier (st_ino is 0 when normal stat() is used, and still is)
* W32 File attributes (which stat() doesn't report); in particular, this allows
symlinks to be correctly identified
* Full, 64-bit time, guaranteed (g_stat() uses 32-bit st_*time on 32-bit Windows)
* Allocated file size (as a W32 replacement for the missing st_blocks)
st_mode remains unchanged (thus, no S_ISLNK), so when these are given back to
glib users (via g_stat(), for example, which is now implemented by calling g_win32_stat_utf8),
this field does not contain anything unexpected.
g_lstat() now calls g_win32_lstat_utf8(), which works on symlinks the way it's supposed to.
Also adds the g_win32_readlink_utf8() function, which behaves like readlink()
(including its inability to return 0-terminated strings and inability to say how large
the output buffer should be; these limitations are purely for compatibility with
existing glib code).
Thus, symlink support should now be much better, although far from being complete.
A new W32-only test in gio/tests/file.c highlights the following features:
* allocated size
* 64-bit time
* unique file IDs

Very many testcases, some GLib tools (resource compiler, etc) and
GApplication were calling g_type_init().
Remove those uses, as they are no longer required.
